What is the difference between China 6a and China 6b?
1 Answers
China 6A and 6B differ in their implementation timelines and emission standards. Additional details are as follows: 1. Definition of China 6: The China 6 Motor Vehicle Pollutant Emission Standards (Phase VI) were established to implement the Environmental Protection Law of the People's Republic of China and the Air Pollution Prevention and Control Law of the People's Republic of China. These standards aim to prevent environmental pollution from exhaust emissions of compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health. The standards consist of two parts: "Limits and Measurement Methods for Emissions from Light-Duty Vehicles (China 6)" and "Limits and Measurement Methods for Emissions from Heavy-Duty Diesel Vehicles (China 6)". 2. Interpretation: The Ministry of Environmental Protection will actively coordinate with relevant departments to ensure the implementation of the China 6 standards for light-duty vehicles. It will further strengthen inspections of vehicle environmental compliance, promote the upgrading of vehicle fuels, and effectively improve urban air quality.
